鋼波紋涵管、波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)、鋼制波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)洞(dong)、金(jin)屬波(bo)(bo)紋(wen)(wen)涵(han)管(guan)(guan)結構(gou)受力(li)情況公道(dao)，荷載(zai)分布平均，并有一定(ding)的抗變形能力(li)。涵(han)管(guan)(guan)、波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)、鋼制波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)洞(dong)、金(jin)屬波(bo)(bo)紋(wen)(wen)涵(han)管(guan)(guan)采用尺度化設計(ji)，出產、設計(ji)簡樸，出產周期短。波(bo)(bo)紋(wen)(wen)涵(han)管(guan)(guan)有利(li)于改(gai)善軟土(tu)地基結構(gou)物與路堤接壤處的"錯臺"現象，進步行車的恬靜度與安全性，減少工后營(ying)運、養(yang)護本錢。

鋼波紋涵管有效面積的不亂性會直接影響著儀表的精度

進(jin)行工廠集中化出產(chan)，出產(chan)不受環境(jing)影(ying)響，有利降低本錢、控(kong)制(zhi)質(zhi)量。涵管(guan)、波(bo)紋(wen)管(guan)涵、鋼(gang)制(zhi)波(bo)紋(wen)管(guan)涵洞(dong)、金屬波(bo)紋(wen)涵管(guan)現場(chang)安(an)裝利便(bian)，不需使(shi)用(yong)大型設備。解決北方嚴寒地區（霜凍）對(dui)橋梁和管(guan)涵砼(tong)結構的破壞題(ti)目(mu)。減少或(huo)根本舍棄了常規(gui)建材(cai)，如(ru)水泥、黃砂、石子、木(mu)材(cai)的使(shi)用(yong)，環保(bao)意義深(shen)遠。

涵管(guan)、波(bo)紋(wen)管(guan)涵、鋼制(zhi)波(bo)紋(wen)管(guan)涵洞、金(jin)屬(shu)波(bo)紋(wen)涵管(guan)適應地基(ji)變形能力強，對地基(ji)承(cheng)載(zai)能力、平整度要求較低，工(gong)(gong)(gong)程實(shi)際(ji)造價(jia)比同類跨(kua)徑的橋、涵洞相近(jin)或較低。施工(gong)(gong)(gong)工(gong)(gong)(gong)期短是顯著的上風，土建工(gong)(gong)(gong)程與管(guan)節安裝可分開實(shi)施。

對鋼波紋涵管有(you)效(xiao)(xiao)面積(ji)(ji)提出的要(yao)(yao)求及其計算(suan)方法取(qu)決于(yu)(yu)波(bo)紋(wen)管(guan)的用(yong)(yong)途。假如波(bo)紋(wen)管(guan)用(yong)(yong)作彈性密(mi)封件或(huo)管(guan)路熱補償(chang)時(shi)，有(you)效(xiao)(xiao)面積(ji)(ji)的意義僅在于(yu)(yu)用(yong)(yong)來計算(suan)波(bo)紋(wen)管(guan)成形時(shi)的軸(zhou)向力(li)(li)和使(shi)用(yong)(yong)系統中的推(tui)力(li)(li)。波(bo)紋(wen)管(guan)的有(you)效(xiao)(xiao)面積(ji)(ji)計算(suan)值(zhi)與(yu)實測值(zhi)之(zhi)間急有(you)一些差別。一般情(qing)況下(xia)用(yong)(yong)專用(yong)(yong)公(gong)式計算(suan)波(bo)紋(wen)管(guan)的有(you)效(xiao)(xiao)面積(ji)(ji)，是可以知足需要(yao)(yao)的。當波(bo)紋(wen)管(guan)用(yong)(yong)于(yu)(yu)力(li)(li)平衡(heng)儀表和需要(yao)(yao)將壓力(li)(li)轉(zhuan)換(huan)為力(li)(li)的場臺，應正確(que)確(que)定(ding)其有(you)效(xiao)(xiao)面積(ji)(ji)，要(yao)(yao)求逐個進(jin)行丈量。

波紋管(guan)(guan)的體積(ji)有(you)效(xiao)面積(ji)波紋管(guan)(guan)在外力或(huo)壓(ya)差作用下，其體積(ji)變(bian)化量與相應的有(you)效(xiao)長度的變(bian)化量之比值稱為體積(ji)有(you)效(xiao)面積(ji)。波紋管(guan)(guan)有(you)效(xiao)面積(ji)的計(ji)算

波(bo)紋(wen)(wen)管用(yong)(yong)于力(li)(li)平(ping)衡式儀表時，其有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)的(de)(de)不(bu)(bu)亂(luan)性會(hui)直接影(ying)響著儀表的(de)(de)精度。所以在這種場合不(bu)(bu)但(dan)要求(qiu)波(bo)紋(wen)(wen)管具有(you)(you)公道(dao)的(de)(de)有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)，而(er)且(qie)還要求(qiu)有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)在工作(zuo)過程中不(bu)(bu)隨工作(zuo)前提而(er)變化。有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)的(de)(de)概念和有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)的(de)(de)變化有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)是一個等效(xiao)(xiao)(xiao)(xiao)的(de)(de)面(mian)(mian)(mian)(mian)(mian)積(ji)，壓力(li)(li)作(zuo)用(yong)(yong)在這個面(mian)(mian)(mian)(mian)(mian)積(ji)上將產生(sheng)相等的(de)(de)軸向力(li)(li)。一般情況下，跟(gen)著內壓力(li)(li)的(de)(de)增(zeng)大，波(bo)紋(wen)(wen)管有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)變小，面(mian)(mian)(mian)(mian)(mian)隨外壓力(li)(li)的(de)(de)增(zeng)加，有(you)(you)效(xiao)(xiao)(xiao)(xiao)面(mian)(mian)(mian)(mian)(mian)積(ji)變大。

有(you)效面(mian)積是(shi)波(bo)紋管(guan)的(de)基本機能參數之(zhi)一，它表征(zheng)波(bo)紋管(guan)將壓力轉換為(wei)集中力的(de)能力，在(zai)利用(yong)波(bo)紋管(guan)把壓力變(bian)成集中力輸出的(de)場(chang)合，有(you)效面(mian)積就是(shi)一個重要參數。
